Title

Effects of titanium dioxide nanoparticles and sheep manure biochar on the behavior of methylene blue organic contaminant in sandy loam and loam soils

Pages

  59-72

Abstract

 The present study aimed to evaluate the effects of Titanium Dioxide Nanoparticles (T: 1 and 3%), sheep manure Biochar (B: 1 and 3%), and their combination (T0. 5% + B0. 5% and T1. 5% + B1. 5%) on the degradation/sorption of Methylene Blue (MB: 100, 200, and 300 mg/kg Soil) in sandy loam (SL) and loam (L) Soils with variable light radiation (Ultraviolet(UV) and visible(VS)). According to the results, the application of T (especially with UV radiation exposure), B, and their combination significantly reduced the MB concentration in the Soils compared to the control treatment (without T and B). In addition, the combined application of T and B (T1. 5% + B1. 5%) was significantly more efficient than the other treatments in the reduction of the MB extraction in the studied Soils. However, B and T application decreased the Soil MB concentration, but due to the competition between the ions in the Soils and MB for adsorption on the B and T surfaces, insufficient water in the Soils to form appropriate amounts of degradable hydroxyl radicals, low absorption of UV radiation by T (due to the high thickness of the Soil layer), and consumption of large amounts of T for Soil organic matter degradation, the efficacy of these amendments decreased. Moreover, lack of using specialized Biochar for this cationic contaminant (modification of the B functional groups) diminished the efficiency of this adsorbent in the Soil, which requires further investigations. . .
